In accord nce withthe provisions of lthe patent statutes, Ihave 'described the principleof operation of. my invention, together with the apparatus which I nowconsider to. represent the vbest embodiment thereof; but I desireto haveit understood that the apparatus shownis only illustrative, and that theinvention can be carried out by other means.

What l claim as new-and desire to secure bv Letters Patent of the UnitedStates, is

l. The combination with a stem turbine supplying exhaust steam toconsumption devices, 'of a speed governor, a valve for admitting highpressure steam to the turbine, a valve admitting lhigh -pressure steamto the exhaust pipe, and a valve Jfor blowing 0E steam Jfrom 'said pipe,all three valves/ being controlled by the speed governor; f

3. The combination 'with-a steam turbine..

5. The combination with a steam turbine supplying exhaust steam toconsumption devices, of a valve admitting high ressure steam to ,theexhaust pipe, a blow-olii' valve a speed governorior the turbine, apressure 'responsive deviceiconnected with the. exhaust pipe, andoperative connections between said valves andtli'e governorand pressureFegulator whereby an increase o load on the turbine or a decrease in thedemand of the consumption devices will cause an opening of the blow-oli'valve, and opposite conditions an opening of the high pressure steamvalve.
